Presentation Transcript

  1. MIRA36 Band Cloud Radar • Vertically pointing (ground based, no scanning unit) • Ka-Band 35.5 GHz  8.6 mm • Magnetron, 30 kW Pulse Power 1/1000 • Rang resolution 30 m (w.o. pulse comp.) • Dual polarization receiver • -45 dBZ @ 10 km and 10 s Averaging • PRF = 5 kHz  +/- 11 m/s

  2. Ice Cloud Water Cloud Maybe Clouds Rain Plankton

  3. Different LDR Melting Layer High LDR Rain Low LDR High LDR in Plankton Mix LDR Un-Detetable

  4. Multi Peak Moment Estimation: spcs2dmp Remove Noise + Ground Clutter Find Peaks, Separate in doubt Calculate for each Peak: SNR, VEL, RMS, LDR Classification: mmclx Per peak Classification if possible based on: Individual Moments SNR, VEL, RMS, LDR General Weather + Melting Height 3-D Cluster for Classification of the rest Melting height detection from hydro meteor data (more details in the extended abstracts) Structure of the Algorithms

  5. Range Gate 20 (840 m) 12:54:40 – 12:54:50 July 02 2007 Lindenberg Co-Spectrum Cross-Spectrum Big LDR SNR-Spectrum [dB] Small LDR Detection Threshold Rain Plankton Vertical Doppler-Velocity [m/s]

  6. Range Gate 94 (3060 m) 12:54:40 – 12:54:50 July 02 2007 Lindenberg SNR-Spectrum [dB] Rain Rain Drizzle Vertical Doppler-Velocity [m/s]

  7. Range Gate 103 (3330 m) 12:54:40 – 12:54:50 July 02 2007 Lindenberg SNR-Spectrum [dB] Big LDR Small LDR Melting Layer Drizzle Vertical Doppler-Velocity [m/s]

  8. Cloud not Plankton Detected not Detected Clean Rain Melting Height External

  9. Cloud Top seen by Cloud Radar Cloud Base seen by Ceilometer

  10. Super-Cooled Water

  11. Plankton detection works good (in most cases). Melting layer detection has to be improved. Separation between rain and cloud has to be improved. More target types. Investigate double peaks with different LDR Governmentally founded 2 year research project by METEK and the ZIB in Berlin. Conclusions / Outlook
